Table 2 Analytical data of the samples by the "Dipole CHIM" at the Yingezhuang gold deposit

CHIM method involves extracting metal ions of electromobile forms in either anodes or cathodes, facilitated by a man-made electric field. This paper presents two newly developed CHIM alternatives that are electrified by a low voltage dipole. The firstly improved technique enables cationic ions to be extracted in a single cathode, whereas the secondly improved technique allows both anionic and cationic species to be extracted simultaneously in an anode and in a cathode. Compared with the traditional CHIM methods, the innovative techniques developed in this paper are characterized by simple instrumentation, low cost and easy operation in field, and in particular enables simultaneous extraction of anionic and cationic species of elements, from which more information can be derived with higher extraction efficiency. Field tests at several well-known mine areas in China confirm the effectiveness and efficiency of the new techniques in exploring for deeply buried ore bodies.

Estudios de eficiencia en el uso de la luz y estimaciones de biomasa en cultivos energéticos de Salix sp. en Central New York, USA

La productividad es un factor importante que influye en la viabilidad económica de un cultivo energético de sauce y maximizarla se convierte en un tema primordial. Esta investigación está directamente relacionada con dicha característica. La productividad varía según los clones cultivados, que pueden ser mejorados y seleccionados genéticamente. Los programas genéticos requieren de una información previa (productividad media en función del porte y número de los tallos, características de las hojas, resistencia a las plagas, etc.) que ayudará a obtener clones más productivos y resistentes. Por ello, nuestra investigación consta de dos estudios: (1) Evaluación de la eficiencia del uso de la luz o LUE (Light Use Efficiency). El incremento de biomasa y la eficiencia del uso de la luz (LUE) fue estudiado en 15 clones del genero Salix durante los meses de junio a septiembre de 2011 en Belleville (Central New York, USA). Los objetivos de este estudio fueron: (1) Evaluar la eficiencia del uso de la luz en la explicación a la variación en la producción de biomasa y (2) Determinar si existen diferencias significativas entre clones evaluando el índice de área foliar (LAI) y algunos componentes de las hojas (N, P, K,…). Se concluye que la variación de biomasa está relacionada con la cantidad de luz interceptada y con la eficiencia de su uso. Dicha información debe de ser transferida para ayudar a mejorar genéticamente los futuros clones a comercializar, con el fin de maximizar la productividad y aumentar la resistencia a plagas. (2) Estimación de biomasa a través de modelos de regresión. Los estudios de investigación relacionados con la productividad requieren estimaciones no destructivas de la biomasa aérea. Sin embargo, el nivel de precisión requerido y la inversión de tiempo son excesivos para operaciones comerciales con grandes extensiones (plantaciones de 10.000 ha). Por esta razón, se estudia el nivel de especificidad (específico, intermedio y general) en la toma de datos de campo sobre los mismos 15 clones (12 de ellos se pueden agrupar en 5 grupos según su genotipo origen) del genero Salix, empleados en el estudio anterior. Para todos los niveles estudiados se observaron diferencias significativas. Pero desde nuestro punto de vista, las diferencias obtenidas no son relevantes. Para validar los modelos finalmente seleccionados se calcularon los porcentajes de error entre la biomasa estimada por los modelos de regresión calculados y la biomasa real obtenida tras los pesajes de biomasa, todo ello se realizó para cada clon según nivel de especificidad. ABSTRACT Productivity is an important factor in the economic viability of a willow crop´s, therefore, maximize it becomes a major factor. This study is directly related to this feature. Productivity, among other factors, may vary depending on different clones, which can be improved and selected genetically. Genetic programs require prior information (average productivity, size and number of stems, leaf characteristics, resistance to pests, etc.) to help you get more productive clones resistant to local pests. Our research consists of two studies: (1) Evaluation of the efficiency of use of light (LUE, Light Use Efficiency). The increase of biomass and light use efficiency (LUE) was tested on 15 clones of the genus Salix during June and September 2011 in Belleville (Central New York, USA). The objectives of this study were: (1) evaluate the light use efficiency and its relationship with the variation in biomass production and (2) determine whether there are significant differences between clones evaluating the leaf area index (LAI) and some traits of the leaves (N, P, K). We studied the correlation with the light use efficiency. It is concluded that the variation of biomass was related to the amount of light intercepted and its efficiency. Such information must be transferred to help improve future genetically clones to market in order to maximize productivity and increase resistance to pests. (2) Estimation of biomass through regression models. Research studies related to productivity estimates require precision and non destructive biomass. However, the level of accuracy required and the investment of time are excessive for large commercial operations with extensions (plantations of 10,000 ha). Precisely for this reason, we study the level of specificity (specific, intermediate and general) in making field data on the same 15 clones (12 of them can be grouped into five groups according to their genotype origin) of the genus Salix, employees in the previous study. For all levels studied some significant differences were observed. But from our practical standpoint, the differences are not relevant. Finally, to validate the selected models, we calculated the percent of bias between estimated biomass (by the regression models) and real biomass obtained after the weighing of biomass, all this process was done for each clone by level of specificity.

Medidas de la eficacia de los sistemas de intercambio electrónico de datos basados en la especificación ASD 2000M

La Especificación Aeroespacial y de Defensa 2000M, también conocida como S2000M, es un protocolo de intercambio electrónico de datos utilizado en el apoyo logístico de equipos de defensa. La S2000M, resultado de un trabajo conjunto entre Fuerzas Armadas (FFAA) y empresas de Naciones diversas desarrollado durante las últimas cuatro décadas, define tanto los procesos para la adquisición y mantenimiento de componentes militares, como los mensajes normalizados en apoyo de dichos procesos. Equipos de trabajo constituidos por representantes de las citadas FFAA e industria mantienen actualizada la S2000M, por lo que el protocolo evoluciona continuamente con objeto de adaptarse a las necesidades que puedan surgir. Como consecuencia de dicha actualización, existen diversas versiones de la S2000M actualmente en servicio, y este trabajo se basa en la versión denominada 2.1, si bien, una parte importante de las conclusiones del estudio pueden aplicarse a otras versiones del protocolo. A través de los años, la S2000M se ha convertido en un elemento esencial del comercio electrónico de piezas de repuesto y de servicios de mantenimiento y reparación de modernos sistemas aeronáuticos Europeos tales como los aviones de combate Typhoon, Tornado y Rafale, el avion de transporte A400M y los helicópteros NH90 y Tiger, por lo que la S2000M constituye un elemento esencial en el apoyo logístico necesario para asegurar la disponibilidad operativa de dichos sistemas. Así mismo, la S2000M juega un papel fundamental en el comercio electrónico entre las principales empresas aeronáuticas europeas y las organizaciones logísticas de defensa de Naciones tales como Alemania, España, Francia, Holanda, Italia, etc. En consecuencia, la importancia de la S2000M en aspectos tales como logística, nivel de operatividad de los sistemas de armas mencionados, comercio electrónico y sistemas de información es manifiesta, por lo que resulta necesario evaluar la eficacia y eficiencia del protocolo para optimizarlo al máximo. Con este propósito, el presente trabajo estudia la S2000M con objeto de encontrar una respuesta a la pregunta que ha constituido la base de la investigación: ¿Cómo medir el éxito de la Especificación Aeroespacial y de Defensa S2000M? Como la S2000M se utiliza para intercambiar información logística en formato electrónico entre organizaciones y entidades por medio de documentos estructurados y de procesos automatizados, los sistemas de información juegan un papel fundamental en este trabajo. En consecuencia, la base teoríca para tratar de responder a la pregunta anteriormente citada se sustenta en las investigaciones en curso sobre el éxito de los sistemas de información, adaptadas a la problemática específica del protocolo S2000M. Para finalizar, es importante mencionar que debido a que la investigación sobre la S2000M es prácticamente inexistente, este trabajo se centra en un área específica de conocimiento hasta ahora casi inexplorada. El resultado de la investigación se materializa en una serie de propuestas teoricas y prácticas con las que se contribuyen al desarrollo de tres áreas de conocimiento: S2000M, Sistemas de Información e Intercambio Electrónico de Datos. Asimismo, se proponen nuevas áreas de estudio en las tres áreas mencionadas. ABSTRAC The Aerospace and Defence Specification 2000M, in short S2000M, is an Electronic Data Interchange (EDI) standard used in the logistic support of defence equipment. The S2000M is the result of the joint effort undertaken by the Armed Forces and industry of several Nations over the last four decades. The protocol defines the business processes for the supply, maintenance and repair of military components, as well as the standard messages on support of the said processes. Representatives from industry and military keep the S2000M up-to-date and therefore, the protocol evolves continuously to support new requirements that may arise. Consequently, there are different versions of the standard currently available and this study is about one of them, precisely, Revision 2.1; however, many of the research outcomes are also be valid for other versions of the protocol. Through the years, the S2000M has become an essential element for the electronic trade of spare parts and repair services on support of modern European aeronautical systems such as the fighters Typhoon, Tornado and Rafale, the airlifter A400M and the helicopters NH90 and Tiger. As a result, the S2000M is at the center of the logistic support required to ensure the operational availability of these systems. Further, the protocol plays a key role in the electronic exchanges among main European aeronautical players and defence logistics organizations from Nations such as France, Germany, Italy, Netherlands, Spain, etc. Therefore, the significance of the S2000M on the operational availability of the mentioned weapon systems, and in logistics, electronic business and Information Systems (IS) terms is noticeable, and it is then worth evaluating how the S2000M is doing with respect to its effectiveness and efficiency in order to improve these two areas as much as possible. To this end, this work analyzes the S2000M with the aim to find a response to the following research question: How to measure the success of the Aerospace and Defence Specification 2000M? As in the end the S2000M is about the electronic exchange of logistics information among organizations and firms by means of standard messages and processes automation, IS are at the core of this dissertation. For that reason, the theoretical foundation to tackle the research question rests on the ongoing stream of research on IS success, which will be extended to take into consideration the S2000M standpoint as well. Last, it is worth noting that due to the practically inexistent research on the S2000M M, this investigation help filling a gap in this domain. The outcomes from this study materialize in a number of conceptual and practical proposals that contribute to the theory and practice on three main knowledge areas, that is, S2000M, IS and EDI. Further, this work opens the door for further research in the said or related fields.

Interlibrary loan in primary access libraries: challenging the traditional view

Introduction: Primary access libraries serve as the foundation of the National Network of Libraries of Medicine (NN/LM) interlibrary loan (ILL) hierarchy, yet few published reports directly address the important role these libraries play in the ILL system. This may reflect the traditional view that small, primary access libraries are largely users of ILL, rather than important contributors to the effectiveness and efficiency of the national ILL system.

Caracterização de nanopartículas pDNA-protamina e pDNA-protamina-lipossoma e avaliação da eficiência de entrega gênica a células de mamífero.

Em estudos de terapia gênica e vacinação por DNA, a eficiência e a segurança dos vetores que transportam o material genético terapêutico possuem papel fundamental. Vetores não virais são considerados mais seguros, mas menos eficientes em relação aos vetores virais. Em parte, isso se deve à falta de estudos sistemáticos e comparativos no que diz respeito às características físico-químicas desses vetores quando em soluções biológicas e o efeito delas sobre a eficiência de entrega gênica. O objetivo deste trabalho é avaliar o efeito do pH, da força iônica e do tipo tampão de complexação sobre as características físico-químicas de nanopartículas pDNA-protamina e pDNA-protamina-lipofectamina, visando à entrega gênica para diferentes linhagens celulares. Para isso, nanopartículas formadas em diferentes condições foram caracterizadas através de ensaios de espalhamento dinâmico de luz (DLS) e potencial zeta. Os estudos indicaram que o pH, a força iônica, o tipo de tampão e a presença de meio de cultura e soro no ambiente de complexação alteram significativamente o tamanho, a polidispersidade e o potencial zeta das partículas formadas. Finalmente, buscou-se avaliar o efeito dessas características sobre a eficiência de transfecção in vitro de células de macrófagos IC21 e células HeLa. Os estudos de transfecção em células Hela indicam que tanto a composição como as condições de formação das partículas influenciam significativamente a eficiência de transfecção.

Análise de métodos de avaliação de eco eficiência.

Para que a sustentabilidade seja gerenciada e praticada de maneira efetiva, ela deve ser mensurada, utilizando-se de métodos de avaliação da sustentabilidade. Estão disponíveis diferentes métodos de avaliação, que geralmente reduzem o resultado desse levantamento à indicadores de desempenho ambiental, econômico e social (POPEA; ANNANDALE; MORISON-SAUNDERSB, 2004). Uma das denominações mais bem aceitas e difundidas para a conjunção da dimensão ambiental e econômica é conhecida por avaliação de eco eficiência (AEE). Eco eficiência é o \"aspecto da sustentabilidade que relaciona o desempenho ambiental de um sistema de produto ao valor do sistema de produto\" (ISO, 2012). Estão disponíveis diferentes métodos de AEE, porém sem evidência das suas semelhanças e particularidades e como essas características influenciam na escolha do método mais adequado de AEE em relação às potenciais aplicações O objetivo desta pesquisa é, portanto, analisar e indicar os tipos de métodos de avaliação de eco eficiência (AEE) mais adequados para ações gerenciais nas quais caibam tais abordagens. Foram selecionados onze métodos de AEE, a partir do estabelecimento de critérios de caracterização desses métodos, a saber: BASF, Bayer, EcoWater, Hahn et al., Kuosmanen e Kortelainen, MIPS, NRTEE, UN ESCAP, UN, TU Delft, e WBCSD. Identificaram-se, ainda, quatro potenciais aplicações: (i) Monitoramento de processo com vistas à melhoria contínua; (ii) Selecção e classificação de produtos; (iii) Atendimento a requisitos legais e outros requisitos; e, (iv) Marketing, rotulagem de produtos e comunicação ambiental. A partir dos elementos metodológicos estabelecidos pela norma ISSO 14045 (2012) e do conhecimento obtido dos métodos de AEE, determinaram-se quatro requisitos pelos quais os métodos e os potenciais aplicações foram avaliados: (i) Tipo de indicador de desempenho ambiental; (ii) Tipo de indicador de valor de sistema de produto; (iii) Abrangência de aplicação; e, (iv) Tipo de indicador de eco eficiência. Aplicando-se estes requisitos nos métodos de AEE e nos potenciais usos, concluiu-se que quanto à aplicações em termos de monitoramento de processos com vistas à melhoria continua os métodos de AEE recomendados foram Bayer, NRTEE, WBCSD e UN. Para situações de seleção e classificação de produtos os métodos BASF, EcoWater, Kuosmanen e Kortelainen, MIPS, Hahn et al., TU Delft, UN ESCAP e UN demonstraram ter boa aderência. No que se refere a usos voltados ao atendimento de requisitos legais e/ou de outras naturezas, os métodos NRTEE, WBCSD e UN são os mais indicados. Em aplicações de marketing, rotulagem e comunicação foram indicados os métodos BASF, EcoWater e MIPS. Finalmente, concluiu-se que, para a escolha adequada da metodologia para uma AEE, conhecimento prévio das características de cada abordagem é necessário.

La evaluación de los aprendizajes en los sMOOC. Estudio de caso en el Proyecto Europeo ECO

El siguiente artículo hace una reflexión crítica sobre los MOOC, prestando especial atención al análisis de los nuevos sistemas de evaluación; en concreto, el método peer to peer, y cómo esto afecta al rol de docentes y estudiantes. El estudio se ha llevado a cabo tomando como referencia dos sMOOC liderados por el Proyecto Europeo ECO (Elearning, Communication and Open-data: Massive Mobile, Ubiquitous and Open Learning). Los resultados que se presentan han sido analizados desde una perspectiva cuantitativa, utilizando como muestra a los miembros de la comunidad de aprendizaje que han participado en ambos cursos. A través de la utilización de un cuestionario se ha podido conocer cómo han valorado su experiencia formativa y su grado de satisfacción. La mitad de los sujetos encuestados ha considerado adecuado y justo el nuevo sistema evaluativo, sin embargo existe otra mitad que lo considera injusto y que tiene lagunas. Se ha abordado la evaluación como una parte intrínseca del proceso educativo y por ello se ha enfatizado en aspectos como el empoderamiento del alumnado, la cultura de la participación y la interacción social, conceptos que nos acercan a nuevos modelos de aprendizaje que potencian el intelecto colectivo y dejan atrás sistemas transmisivos de conocimiento.

A core vocabulary approach for management of inconsistent speech disorder

Developmental speech disorder is accounted for by theories derived from psychology, psycholinguistics, linguistics and medicine, with researchers developing assessment protocols that reflect their theoretical perspective. How theory and data analyses lead to different therapy approaches, however, is sometimes unclear. Here, we present a case management plan for a 7 year old boy with unintelligible speech. Assessment data were analysed to address seven case management questions regarding need for intervention, service delivery, differential diagnosis, intervention goals, generalization of therapeutic gains, discharge criteria and evaluation of efficacy. Jarrod was diagnosed as having inconsistent speech disorder that required intervention. He pronounced 88% of words differently when asked to name each word in the 25 word inconsistency test of the Diagnostic Evaluation of Articulation and Phonology three times, each trial separated by another activity. Other standardized assessments supported the diagnosis of inconsistent speech disorder that, according to previous research, is associated with a deficit in phonological assembly. Core vocabulary intervention was chosen as the most appropriate therapy technique. Its nature and a possible protocol for implementation is described.

An Autonomic Framework for Mobile Cloud Computing

This thesis presents the formal definition of a novel Mobile Cloud Computing (MCC) extension of the Networked Autonomic Machine (NAM) framework, a general-purpose conceptual tool which describes large-scale distributed autonomic systems. The introduction of autonomic policies in the MCC paradigm has proved to be an effective technique to increase the robustness and flexibility of MCC systems. In particular, autonomic policies based on continuous resource and connectivity monitoring help automate context-aware decisions for computation offloading. We have also provided NAM with a formalization in terms of a transformational operational semantics in order to fill the gap between its existing Java implementation NAM4J and its conceptual definition. Moreover, we have extended NAM4J by adding several components with the purpose of managing large scale autonomic distributed environments. In particular, the middleware allows for the implementation of peer-to-peer (P2P) networks of NAM nodes. Moreover, NAM mobility actions have been implemented to enable the migration of code, execution state and data. Within NAM4J, we have designed and developed a component, denoted as context bus, which is particularly useful in collaborative applications in that, if replicated on each peer, it instantiates a virtual shared channel allowing nodes to notify and get notified about context events. Regarding the autonomic policies management, we have provided NAM4J with a rule engine, whose purpose is to allow a system to autonomously determine when offloading is convenient. We have also provided NAM4J with trust and reputation management mechanisms to make the middleware suitable for applications in which such aspects are of great interest. To this purpose, we have designed and implemented a distributed framework, denoted as DARTSense, where no central server is required, as reputation values are stored and updated by participants in a subjective fashion. We have also investigated the literature regarding MCC systems. The analysis pointed out that all MCC models focus on mobile devices, and consider the Cloud as a system with unlimited resources. To contribute in filling this gap, we defined a modeling and simulation framework for the design and analysis of MCC systems, encompassing both their sides. We have also implemented a modular and reusable simulator of the model. We have applied the NAM principles to two different application scenarios. First, we have defined a hybrid P2P/cloud approach where components and protocols are autonomically configured according to specific target goals, such as cost-effectiveness, reliability and availability. Merging P2P and cloud paradigms brings together the advantages of both: high availability, provided by the Cloud presence, and low cost, by exploiting inexpensive peers resources. As an example, we have shown how the proposed approach can be used to design NAM-based collaborative storage systems based on an autonomic policy to decide how to distribute data chunks among peers and Cloud, according to cost minimization and data availability goals. As a second application, we have defined an autonomic architecture for decentralized urban participatory sensing (UPS) which bridges sensor networks and mobile systems to improve effectiveness and efficiency. The developed application allows users to retrieve and publish different types of sensed information by using the features provided by NAM4J's context bus. Trust and reputation is managed through the application of DARTSense mechanisms. Also, the application includes an autonomic policy that detects areas characterized by few contributors, and tries to recruit new providers by migrating code necessary to sensing, through NAM mobility actions.

AVALIAÇÃO DA EFICIÊNCIA MASTIGATÓRIA NA MORDIDA ABERTA ANTERIOR POR MEIO DO DISPOSITIVO ME MASTIG

Este trabalho avaliou a eficiência mastigatória na maloclusão do tipo Mordida Aberta Anterior por meio do Me-mastig, dispositivo que pode ser utilizado no sentido de se mensurar a eficiência da mastigação, prometendo ser uma alternativa prática, rápida e eficiente para o exame da mastigação. O grupo experimental compôs-se de 106 crianças na faixa etária dos 07 aos 11 anos, divididos em 2 grupos, da seguinte forma: (A) Grupo de Mordida Aberta Anterior, contendo 51 crianças e (B) Grupo Controle, com trespasse vertical normal contendo 55 crianças. Procurou-se avaliar a eficiência mastigatória das crianças dos dois grupos e comparar os resultados, que mostraram que a mastigação do grupo mordida aberta anterior foi menos eficiente quando comparada à do grupo controle; fato que se pode explicar pelas características faciais dos indivíduos portadores da maloclusão estudada e também características da própria maloclusão de mordida aberta anterior. Conclusões, a mordida aberta anterior é responsável por uma diminuição significativa da a Eficiência Mastigatória e o dispositivo Me-mastig se mostrou um método eficaz, de fácil utilização e não dispendioso que pode ser usado na clínica diária para se medir ou avaliar a Eficiência Mastigatória.

A genetic algorithm to optimise the component placement process in the PCB assembly

In printed circuit board (PCB) assembly, the efficiency of the component placement process is dependent on two interrelated issues: the sequence of component placement, that is, the component sequencing problem, and the assignment of component types to feeders of the placement machine, that is, the feeder arrangement problem. In cases where some components with the same type are assigned to more than one feeder, the component retrieval problem should also be considered. Due to their inseparable relationship, a hybrid genetic algorithm is adopted to solve these three problems simultaneously for a type of PCB placement machines called the sequential pick-and-place (PAP) machine in this paper. The objective is to minimise the total distance travelled by the placement head for assembling all components on a PCB. Besides, the algorithm is compared with the methods proposed by other researchers in order to examine its effectiveness and efficiency.

Simulation based knowledge elicitation:effect of visual representation and model parameters

Since much knowledge is tacit, eliciting knowledge is a common bottleneck during the development of knowledge-based systems. Visual interactive simulation (VIS) has been proposed as a means for eliciting experts’ decision-making by getting them to interact with a visual simulation of the real system in which they work. In order to explore the effectiveness and efficiency of VIS based knowledge elicitation, an experiment has been carried out with decision-makers in a Ford Motor Company engine assembly plant. The model properties under investigation were the level of visual representation (2-dimensional, 2½-dimensional and 3-dimensional) and the model parameter settings (unadjusted and adjusted to represent more uncommon and extreme situations). The conclusion from the experiment is that using a 2-dimensional representation with adjusted parameter settings provides the better simulation-based means for eliciting knowledge, at least for the case modelled.

An Investigation of the Irish Road Haulage Industry’s External Environment

The movement of goods is of critical importance to an economy, especially one, which is dependent on international trade such as Ireland. Considering Irelands distribution of manufacturing and other organisations throughout the country, many firms are dependent upon road haulage effectiveness and efficiency. In recent times there has been somewhat of a growing unease in the road haulage industry in relation to increasing cost, squeezing profit margins even tighter. An understanding of the Irish road haulier’s business environment would undoubtedly shed greater light onto their situation. The paper addresses this issue with an analysis of the industry’s competitive environment. The first step of the research methodology was an intensive search for pertinent literature, from which a limited amount of information was obtained. A confined amount of primary research was then carried out. Purposive sampling was used to establish the required respondents. The techniques used were the research conversation approach in combination with semi-structured interviews. Following this a structured postal questionnaire was issued to obtain quantitative statistics. The preliminary results of which are outlined. The analysis identifies a number of issues within the Irish road haulage industry. The paper concludes with the findings that the Irish road haulage industry is at present a brutally competitive environment due to its fragmented nature and the power of its customers. It also identifies the need for further research in order to establish the validity of certain points and issues.

Attributed graph kernels using the Jensen-Tsallis q-differences

We propose a family of attributed graph kernels based on mutual information measures, i.e., the Jensen-Tsallis (JT) q-differences (for q  ∈ [1,2]) between probability distributions over the graphs. To this end, we first assign a probability to each vertex of the graph through a continuous-time quantum walk (CTQW). We then adopt the tree-index approach [1] to strengthen the original vertex labels, and we show how the CTQW can induce a probability distribution over these strengthened labels. We show that our JT kernel (for q  = 1) overcomes the shortcoming of discarding non-isomorphic substructures arising in the R-convolution kernels. Moreover, we prove that the proposed JT kernels generalize the Jensen-Shannon graph kernel [2] (for q = 1) and the classical subtree kernel [3] (for q = 2), respectively. Experimental evaluations demonstrate the effectiveness and efficiency of the JT kernels.
